With increasing environmental pollution,CO2 emission reduction becomes emergent. But an over-emphasis of resource policy design on the socio-economic impacts leads to less concern on CO2 emissions and environmental benefits,which is not harmful to the sustainable development of the society and ecological civili-zation. The paper builds a dynamic computable general equilibrium model ( CGE) to analyze the impacts of resource tax rate adjustment and resource subsidies on emissions reduction and environmental welfare with the scenarios by a quantitative way. The results shows that: resource policy reforms can promote emission reduc-tions and environmental benefits in a long time,and the impacts of different policy designs are different. Coal-resource-tax-rate adjustment can inhibit resource consumption to some extent,improve resource earnings and resource-using efficiency per capita,and reduce environmental losses; resources subsidy policy can improve the environmental quality and environmental welfares. Therefore,coal-resource-tax reform policy should be designed coordinately and completely as soon as possible to guarantee the sustainable development of society.
